"The Electronic Control Unit Port on 2001 Mitsubishi Eclipse"

Black 2001 Mitsubishi Eclipse Left Side View

I want to reset the check engine light. But where can I find the ecu port on my 2001 Mitsubishi Eclipse?

Answer: You don’t need to get to the ECU to reset it. Just disconnect the battery for few minutes and reconnect it. Warning: before you disconnect the battery terminals, make sure you have the programming code (usually found in the owner manual). You need this code to re-program the entire electronic systems in your car. The easiest way is to take it in any dealer/garage and have them reset the ECU.
